【摘要】 文章基于土地利用效益及其对经济、社会、生态三方面的影响，建立土地利用效益评价指标体系，并以熵值法和耦合协调度模型，计算环长株潭城市群8个城市在2007年、2012年、2017年、2022年的土地利用经济效益、社会效益、生态效益耦合协调度。结果表明：环长株潭城市群土地利用三大效益耦合协调度呈现时序增长与空间分异特征；三大效益自身时空差异显著，整体呈增长态势，但区域发展不均衡。更多还原

【Abstract】 Based on the land use benefit and its influence on economics, society and ecology, a land use benefit evaluation index system is built, and the entropy method and coupling coordination model are used to calculate the coupling coordination degree between the economic benefits, social benefits and ecological benefits of land use in eight cities in Changsha-Zhuzhou-Xiangtan urban agglomeration in 2007, 2012, 2017 and 2022. The results show that the coupling coordination degree of the three major land use benefits in Changsha-Zhuzhou-Xiangtan urban agglomeration exhibits temporal growth and spatial differentiation, and the three major benefits themselves show significant temporal and spatial differences, with an overall upward trend but uneven regional development.更多还原
